[TUHS] user struct on SYSIII / V7

Hi, does someone know where "u" is defined on SYSIII or V7? sys/user.h states: extern struct user u; But I wonder where it is defined? On ZEUS I have u.o but I'm not able to correctly disassemble it. Right now I'm guessing that it should be something like: u module $segmented $abs %F600 global _u array [%572 byte] end u But the resulting object (u.o.hd) does not match 100% the existing u.o on the system (u.o.orig.hd). --- u.o.orig.hd 2008-05-16 21:52:12.000000000 +0200 +++ u.o.hd 2008-05-16 21:52:16.000000000 +0200 @@ -3,6 +3,6 @@ 00000020 00 00 00 01 00 00 00 00 01 00 00 00 00 00 00 00 |................| 00000030 00 00 00 02 00 00 00 00 00 00 00 00 1e 00 75 5f |..............u_| 00000040 70 00 00 00 00 00 01 00 00 00 1e 01 75 5f 64 00 |p...........u_d.| -00000050 00 00 00 00 3e 00 f6 00 61 3e 5f 75 00 00 00 00 |....>..a>_u....| +00000050 00 00 00 00 01 00 f6 00 61 01 5f 75 00 00 00 00 |.......a._u....| 00000060 00 00 |..| 00000062
